21 !!DESCRIPTION
22

24 ''s2p'' takes a sed script specified on the command line
25 (or from standard input) and produces a comparable
26 ''perl'' script on the standard output.

41 __-n__

43
44 specifies that this sed script was always invoked with a
45 __sed -n__. Otherwise a switch parser is prepended to the
46 front of the script.

52 specifies that this sed script was never invoked with a
53 __sed -n__. Otherwise a switch parser is prepended to the
54 front of the script.

57 __Considerations__
58
59
60 The perl script produced looks very sed-ish, and there may
61 very well be better ways to express what you want to do in
62 perl. For instance, s2p does not make any use of the split
63 operator, but you might want to.
64
65
66 The perl script you end up with may be either faster or
67 slower than the original sed script. If you're only
68 interested in speed you'll just have to try it both ways. Of
69 course, if you want to do something sed doesn't do, you have
70 no choice. It's often possible to speed up the perl script
71 by various methods, such as deleting all references to $\
72 and chop.
73 !!ENVIRONMENT
74
75
76 s2p uses no environment variables.
